I need a wiring diagram for a 2010 Toro Bronco 42" riding lawn mower. The part number is 13WX78KS011 and it has a Kohler 20 HP engine. I turn the key a nothing happens. The battery is fully charged there is no power to the starter but the other electrical components work.

Hi,
Try this link:

And click the I Accept button. Check the end of it. If your switch has six terminals on back, tell me and I will post the other version's link.
Peace,
